Si Content

For thin-walled casting development of austempered ductile iron (ADI), permanent mold casting and accompanied heat treatment practice were systematically investigated to suppress and/or remove chill defects of ductile cast iron (DCI) with various thickness of 2 to 9 mm and to ensure mechanical properties of the final ADI casting. Si content was increased up to 3.8% to reduce the chill formation tendency under a high cooling rate. The residual Mg content remarkably affected the nodule count, while the nodule size and spherodization were proven to have weak relationships. Austenitizing process followed by austempering was very sensitive to chemical compositions (Si and Sn) and heat treatment temperature. As a practical application, the steel bar coupler for a structural frame was tried to produce without subsequent machining.

Alloy Cast

A356 is a heat treatable cast alloy which has been widely applied in aviation and automobile industries. In this paper a Sb modified A356 alloy cast with permanent mold has been investigated in order to improve its mechanical properties by changing the needle morphology of the eutectic silicon. The results show that a small amount of Sb addition can contribute refined eutectic silicon morphology and enhance the mechanical properties, especially elongation of the A356 cast alloy poured in permanent molds. The optimal addition of Sb is 0.2 wt.%.
